AIS[1] is basically an airplane transponder, but for vessels and I think it broadcasts position along with identification. For safety alone, seems to me that any commercial vessel carrying paid passengers should have one.
But the Reason article is so vague I literally can't tell if they are talking about AIS, or some other bespoke system.

- soneil 4y agoThey really don't explain the difference well. AIS is a local broadcast. It's like having a number plate that's visible from 10 miles away. VMS is 'phone home' system. It's like having a gps tracker with cellular connectivity on your car, reporting into a federal agency (not hyperbole, that's the design goal.)
